# 20170313 bkw:
# - i486 => i586
# - actually use SLKCFLAGS
# - minor grammar fixes in README and slack-desc
# - use long-format github URL
# - use commit date + short hash as VERSION, instead of full hash only.
# - look at upstream, the only 2 new commits are minor edits to README.md,
#   don't bother updating.
